bootloader: Move chip specific things under chip specific folders

- move systick.c under chip specific sources
- move do_jump into chip specific main.c as arch_do_jump
- wrap flash writes to "arch_flash_write" and implement in chip specific main.c
- add bootloader TOC check
- sync image_toc.h with the version currently in use with old bootloader
